Study of elastic modulus of Ti

In this study, titanium alloy Ti(70-x)-Nbx-Ta25-Zr5 (x = 5, 10 at.%) was synthesized using arc melting followed by water cooling and a series of heat treatments, specifically a solution treatment at 950ºC for one hour, water quenching, and aging at 480ºC for twelve hours under an argon atmosphere. The resulting microstructures predominantly exhibited a dendritic β phase, and prior β grain boundaries. Nanoindentation tests indicated that the lowest elastic Young’s modulus recorded for heat-treated sample Ti60-Nb10-Ta25-Zr5 was 66.6 ± 15.2 GPa. The XRD, EBSD and indentation and hardness results are presented in the paper.
